Mike Smith of Ruapehu Alpine Lifts said snow started to fall on Mt Ruapehu around 11pm on Monday night, and had become fairly heavy by yesterday afternoon. Turoa Rd was closed because of snow.
The mountain's Turoa skifield was not due to open until June 25, but Mr Smith said he hoped the snowfall was a sign of good things to come.
"We're pretty heartened - the Niwa climate outlook for autumn and winter was released late last week.
"They're saying the closest climate outlook approximation to recent years was 2008. And that was the best season we'd ever had in terms of snowfall."
Last season was a difficult one because of light snowfall and poor weekend weather.
"But it feels like we had a really nice, very long, warm, dry summer. And it kind of feels like the seasons have normalised a bit."
The weather took another turn when a mini tornado tore the roof off a building in Papatoetoe, trapping a man inside. The tornado struck at Safe Store on Puhinui Rd just after 2.30pm. Fire Service shift manager Jaron Phillips said it was "pretty crazy" and isolated.
He said the person was freed and did not need to be hospitalised.
